1.(-2,7) – (-3,4)
2.(-1) – (+0,8)
3.(1/5) – (-4/5)
4.(-3/4) – (-½)
5.(-0,75) – (- ¾)
6.(-7/4) – (+0,4)
Jawaban:
1.(-2,7) – (-3,4) = +0,7
2.(-1) – (+0,8) = -18
3.(1/5) – (-4/5) = 1/5 + 4/5 = +5/5 = +1
4.(-3/4) – (-½) = -3/4 + 2/4 = -1/4
5.(-0,75) – (- ¾) = -0,75 + 0,75 = 0
6.(-7/4) – (+0,4) = -7/4 – 4/10 = -35/20 – 8/20 = -43/20
